	(d)	Apportionment of Expenses
Where an item of plant is used partly for the purposes of treating, processing or refining of petroleum prior to delivery or in conveying petroleum to the point of delivery to the purchaser, and partly for some other purpose, the amount of the deduction (whether for capital or operating expenditure) which shall be allowed shall be a proportion only of the actual capital or operating expenditure. The apportionment of the actual expenditure shall be made upon the basis agreed between the Producers and the Minister or, in the event that agreement is not reached within 90 days of the commencement of discussions entered into with a view to reaching such agreement, upon the basis determined by the Minister.
	(e)	Sale of Plant
Notwithstanding the provisions of sub-clause (2), if an item of plant is sold by a Producer ("the first Producer") to another Producer, or to a company that becomes a successor or assign of the first Producer under this Indenture ("the second Producer"), the second Producer may only depreciate the plant to the extent to which the first Producer was, immediately before the time of sale, entitled to depreciate the plant under this Indenture.

	(i)	If the Producers or any one or more of them receive any revenue from the use of any plant downstream of the wellhead used for treating processing or refining petroleum sourced from anywhere within the area from time to time comprised in Petroleum Exploration Licences 5 and 6 or any Petroleum Production Licence issued from an area which was comprised in Petroleum Exploration Licences 5 and 6 immediately prior to the time such Petroleum Production Licence was issued, or in conveying such petroleum to the point of delivery to the purchaser (such plant to include but not be limited to part or all of each of the plant at Moomba, South Australia, the plant at Port Bonython in the said State or the pipeline the subject of Pipeline Licence 2) such revenue shall be deemed to be part of the gross sales value of the petroleum to the intent that royalty shall be payable thereon.
	(ii)	Any sums, being sums deemed under sub-clause (3)(g)(i) to be part of the gross sales value of the petroleum, paid by the Producers or any one or more of them in respect of the use of such plant for treating processing or refining such petroleum or in conveying such petroleum to the point of delivery to the purchaser shall be deemed to be an expense under sub-clause (2)(d).
	(iii)	If any such plant is used for treating processing or refining of petroleum sourced from outside of the areas referred to in sub-clause (3)(g)(i) or in conveying such petroleum to the point of delivery to the purchaser any amounts which may be claimed as deductions under this clause (whether such deductions be by way of operating expenditure or capital expenditure) in respect of such plant shall be reduced by the proportion which would be obtained by the method of apportioning costs used by the Producers to ascertain the tolling fee, or on such other basis as the Minister approves, but any revenue received by the Producers or any one or more of them for the use of such plant for the treating processing or refining of such petroleum prior to delivery or in conveying the petroleum to the point of delivery to the purchaser shall not be deemed to be part of the gross sales value of the petroleum.
	(h)	Licence Fees

The Operator shall provide such reconciliation in respect of the period commencing 1st January 1991 and concluding 30th June 1991 on or before 30th July 1991.
	(e)	Each Producer shall not later than thirty (30) days after the completion of each twelve month period during the Royalty Term concluding on each 30th June pay to the Minister the additional royalty calculated in accordance with the reconciliation referred to in sub-clause 4(d) as payable by that Producer.
	(f)	The Minister shall not be concerned to inquire that the royalty has been correctly apportioned as between each of the Producers so long as the aggregate of the royalty so apportioned equals the total amount of royalty payable in accordance with this Clause. The Producers may, however, dispute inter se the correctness of the apportionment of royalty.
	(g)	Provided that royalty has been correctly calculated, each Producer shall only be liable to pay the amount of royalty specified in each royalty return as payable by that Producer. Nothing in this Clause shall confer joint or joint and several liability on the Producers for the payment of royalty.
	(h)	The Producers shall at their cost cause the royalty calculation reconciliations submitted by the Operator to be audited by the auditor appointed by the Operator to audit its own accounts (provided that such auditor must be a duly registered auditor in Australia) and the Operator shall forward a copy of the auditor's report in respect of a particular reconciliation within 3 months of the receipt of such reconciliation by the Minister, such report to be accompanied by a certificate by the auditor that the reconciliation is in accordance with the royalty provisions of this Indenture.
	(i)	If the Minister considers that any matter has been incorrectly calculated in any royalty return, the Minister may recalculate such return and by notice in writing to the Operator within 6 calendar months of the receipt by the Minister of the audit of the relevant royalty return require the Producers to pay within 30 days of the date of such notice the additional royalty calculated by the Minister as payable and in any proceedings before a Court for the review of such determination, the Minister's recalculation shall be deemed to be correct unless the contrary is proved.
	(j)	Either the Producers or the Minister may, notwithstanding the audit of a royalty return, within a period of 5 years of the Minister's receipt of that return, serve notice on the other party seeking to correct an inaccuracy in that return. If the notice is served by the Producers, the Minister may within 90 days of the receipt of the Producers' notice make a determination as to the correctness of the Producers' notice.
	(k)	The Producers or any one of them shall at the request of the Minister or of any person duly authorised in writing by the Minister produce to the Minister or such authorised person such books, accounts and other records (including but not limited to computer records) in the possession or power of that Producer relating to the petroleum and the royalty payable thereon and shall permit the Minister or such authorised person to inspect and make copies of such books, accounts and records.
	(l)	The Minister may require the Operator to prepare and provide to the Minister forecasts of royalty for such periods and to be provided at such times as the Minister may reasonably specify.
	(m)	If the Producers fail to pay any payment of royalty within the time provided by this sub-clause, the Producers shall pay interest on the amount of royalty which should have been paid, calculated on a daily basis from the date such payment should have been made to the date of actual payment, at a rate being the sum of 2% per annum and the long term Australian Government Bond Rate for bonds of a 10 year term as published at the end of the month the payment should have been made. If the long term Australian Government Bond Rate for bonds of a 10 year term ceases to exist or be published then the rate of interest shall be the sum of 2% per annum and the average of the long term Australian Government Bond Rate for bonds of a 10 year term prevailing during the period of 5 years preceding the date on which such rate ceased to exist or be published.
	(5)	General
	(a)	The payment of royalty pursuant to this Indenture shall during the Royalty Term be in substitution for and not in addition to any royalty which would otherwise have been payable under the Petroleum Act, 1940 in respect of the petroleum.
	(b)	On and from the 1st day of January 2001 the Producers shall pay royalty in accordance with the provisions of the Petroleum Act, 1940 or any statute repealing, replacing, amending or consolidating that Act.
	(c)	Notwithstanding anything to the contrary contained in this Indenture no royalty, tax, impost or levy of whatsoever nature or kind other than bona fide charges for services provided by the State shall be payable by the Producers upon any petroleum produced from a State other than South Australia.
	(d)	The Minister may delegate any of his powers contained in this Clause 12; however such delegation shall not derogate from the Minister's ability to exercise such power personally.
	(e)	In making any determination under this Clause, the Minister must take into consideration all relevant factors and make the determination on reasonable grounds.
	(f)	In determining the value of actual sales of petroleum, the full market value of petroleum, or the amount of any expenditure for the purposes of this clause, any GST component is to be ignored.
13.	PIPELINES
